So I know if this is a really silly topic of discussion but I gave it and I wanted to hear other users thoughts. So where do your nicknames come from? I invented my nickname "Jacko" from my first name which is Jaakko and begins with the letter J. The extension of numbers comes from my birth year which is 1990 and though it sounds silly with my nickname it helps other users at recognizing me cause there's a user called Zacko. I find it often very hard to invent a catchy nickname starting with the letter J.
